IMPROVBD WASHING MACHINE.

TO'ALL WHOM IT MAY GONOERN:

Be it known that I, ALEXANDER R. CAMPBELL, of Cheltenham, county of St. Louis, State of Missouri,`

have invented a new and useful -Improved Washing Machine, of which the following is a full, clear, and exact description, reference being had to the annexed drawing, making a part of this specication, in which- Figure 1 represents a sectional elevation .of my invention. u I v Figure 2 represents a detail of same, hereinafter described.

Similar letters indicate like parte. -It consists ofa wooden box, AA, resting upon four legs, two of which are shown atb b', having its sides and hone end-square, while the other makes a circle withthe bottom. The topvis partially covered by a. fixed cover, '0, at the termination of which are placed two standards, one of whichis 'shown at d, which serve as the bearing'sfor a rock-shaft, e, from which extend two radial dash arms, of which oneis seen atf, to whose extremities is attached a`semicircular dasher, E, having avcorrugated surface, the corrugation being extended over the dash-board@ while above g, and separated from it by a slight opening, is another dash-board, h, with alsmooth surface. From the extremity ofthe dash-arms extend two shafts, one of which is seen 'at lc, having their ends connected by the'crossbar M, forming the handle. Two braces, one of which is shown at n, connect these shafts and the dash-arms, and .upon them is placed a cover, o, which, like the dasher and dash-boards, extends acrossthefbox from side to side, `just space enough Vbeing left to allow them to move freely. Tle length of the dash-arms is' such that there is left only space enough'between the da'sher and the circular bottom'and side of the box to allow the dasher to work freely, while-the shafts .are fixed at such an angle as will prevent the dasher from striking too hard against the square 'end of the box. The sides of the box are smooth, but the two ends' and the bottom are corrugated, as shown at p p p. Thefstanda-rds being made to slide in dove-tailed slots, one of which is shownl at g, fig. 1, and in fig. 2, are easily removed whenever it is desired to take out the dasher and frame for any purpose. Handles', two of ywhich are shown at s and t, are fixed on the box, and at i! there is a vent-for the water to escape.

When the machine is to be used, move thedasher from the box by raising-the cross-bar M, the dasher swinging freely onthe rock-shaft, and place the articles to be washed with the water in the box. As .the dasher will notepasseoverthe clothes,-on account of the-small space betweeli it and the bottom,it will be stopped by them, and assume the position, 'for instance, shown by the red line fw, while the shafts take that indicated by the red linea. New, by working the handle up'and down in th'e direction indicated by the arrows z z, the clothes will first be pressed against the square end of the box by the dasher, and then, when this retreats, the suction will draw the clothes back, the clothes being alternately filled 4with water by theone operation and deprived of the water by the other, and in both cases obtaining the benefit of the corrugated bottom by being drawn back and forth over it. l

The advantages of myjnvention consist in entirely obviating any risk of tearing theclothes, however delicate, since the only force acting upon them is the pressure of the dasher and the suction of the water, there being no rubbing except such as is caused by their passing back and forth over thecorrugations. By the` pressure it is evident that the clothes ar'emore thoroughly cleansed than they would be by rubbing, since the water is' forced through them, taking with it all impurities. The dasher being so. hung that it will fall by its own weight, the labor of operating the machine is very slight. No metal being used in the construction of the machine except the brass screws which hold thevarirs parts, there is no liability to injury from rust.

What I claim as my invention, and desire to secure by'liettersl Patent, is-

The rock-shaft e, semicircular corrugated dasher E, corrugated dash-board g, smooth dash-board h, shafts 7c, cross-bar M, braces n, cover o, standards d, dove-tailed slots g, and the corrugated circular and square ends of a washing machine, all in combination, when' constructed and operating substantially as shown and specified;
